"I was scammed at a nightclub in Istanbul."

"I met some other travellers and I joined their private table for most of the night. At the end, I was left with a $4,000 USD bill. In reality, the cost should have been in the $400 USD range.

[...]

"When the bill came, the place cleared out and I was escorted to the ATM machine. My life threatened along the way. The ATM denied me so I was forced to call my credit card company. They denied raising my credit limit to pay the club.

"At the end of the day, I convinced them I had another credit card at my hotel. They escorted me to the hotel, I told the front desk what was up and they locked the doors and called the cops. Turns out the group that had me was recently busted with large amounts of money, drugs, and weapons." - HereIsYourBankersBox

"I've heard that stray dogs are kind of the norm in Latin American countries, and most of the ones I encountered didn't want anything to do with anyone passing by.

"However, there was one stray that I passed frequently while walking to a project I was working at and he was extremely aggressive, to the point that I started carrying rocks in my bag in case he chased me. He would follow me for blocks, remaining hidden in a yard until I passed by. He'd bare his teeth and growl, he also slobbered a lot.

"There were restaurants that I could be taken to for a business lunch, but only lunch. They were closed to me at night for dinner because I was not Japanese. Other places I wasn't allowed in under any circumstances. The local business partners wouldn't even discuss it. They would just say — 'no, no, not possible' — and look around uncomfortably." - beachedsailor

"Not to mention that the weather changes every 15 minutes in the winter between whiteout, heavy snow, hail, rain. There is literally nowhere to pull over for hours, and you just have to try and keep to the road and hope you don't die." - Samcrash76
